The real intolerance here is being displayed by the left. They cannot allow groups to exist that refuse to give in to the Left's agenda and that is how it has always been. Conservatives might stall them but has never stopped them on social controversies.
Abortion, bussing, segregation, destroying the differences between genders, etc the left has triumphed in all these things with the conservatives eventually going silent because their assinine and incompetent 'leaders' give up (like Ryan on DADT). The left is willing to work with such conservative leaders, but the ones who refuse to budge get marginalized like pro-lifers are today. In all these issues the Biblical church eventually went along, except for abortion, but they have been so thoroughly defeated on that issue and abortion almost 100% guarranteed in every trimester, that the left considers the pro-life movement to be a tolerable and increasingly irrelevant minority.
But just as the left wants ALL women to be able to get what they want, they also want gays to get 100% of what they want which is acceptance as normal from EVERYONE, no exception. And the audacity of some Biblical churches to actively continue to fight on this issue so long is intolerable to the left.So they attack every public person and every public group that still opposes them. The Boy Scouts, being largely sponsored by local churches, refelects those local church values.
The Boy Scouts will either eventually accept openly homosexual 'scouts' or the left will hound them into extinction and feel totally self righteous while doing so. Within ten years every public GOP 'conservative' politician will have endorsed homosexual marriage and it will be legal in every state or the left will go psychotic on everyone.
They canot allow true freedom of assembly which requires the ability to refuse membership to those opposed to the groups core values, whether it is being for or against tax increases, a favorite sports team, the worship of God, or anything else. If there is no sign the group in question is not getting on board then the left will destroy it. Just look at how the Mormon church was threatened with loss of its tax exempt status if it continued to refuse membership to blacks in its priesthood.
Biblical churches need to learn how to go underground again and not be formally organized any more.
